Did you ever wonder what might happen if mankind ever exceeded the speed of light? Here is a profound story based on that thought--a story which may well forecast one of the problems to be encountered in space travel.

efore we had completed man's first trip through hyperspace. We were now making the first landing on an inhabited planet of another sun. All the preliminary investigations had been made via electronspectroscopes and electrontelescopes from the stellatomic.

We knew that the atmosphere was breathable and were reasonably certain that the peoples of the world into whose atmosphere we were dropping were at peace. We went unarmed, just the two of us; it might not be wise to go in force.

We were silent, and I know that Harry Albrecht was as perplexed as I was over the fact that our all-wave receivers failed to pick up any signs of radio communication whatever. We had assumed that we would pick up signals of some type as soon as we had passed down through the unfamiliar planet's ionosphere.

The scattered arrangement of the towering cities appeared to call for radio communications. The hundreds of atmosphere ships flashing along a system of airways between the cities seemed to indicate the existence of electronic navigational
